Louis Pasteur was born in 1822 in a little town in France. As he grew up, he loved to paint. He loved to look at the world around him. When he went to college in Paris, he showed interest in looking through a microscope. A microscope makes things look a lot bigger; it lets you see things you can’t see just with your eyes. Looking through a microscope, Pasteur found a living world in a drop of water. He saw and drew pictures of the small living things －he called them “microbes” or “germs”－that crowded in a drop of water.

    One day a winemaker came into the lab, hoping that someone could help him with his problem. “Sometimes my wine tastes delicious, but sometimes it turns sour（酸的）,” he said to Pasteur. “Can you help me find out why?”

    Pasteur put some drops of the wine under the microscope. He noticed that the sour wine had some unusual germs. If he killed these germs, maybe he could keep the wine from turning sour. He experimented （试验）with different ways to kill the germs. In the end he found heating （加热）the wine seemed to work best. The winemaker tried it, and every bottle of wine tasted good.

    Pasteur’s idea worked for other people, too. When farmers heated milk, it didn’t sour so quickly. When breweries （啤酒师）heated beer, it tasted better. People called the process （过程）“pasteurization” － heating a liquid to kill bad germs. Aren’t you glad that the milk you drink has been pasteurized?

Mrs Elise was my teacher in the fourth grade. One day at lunch time, I was getting ready to eat my tuna fish (金枪鱼) sandwich and suddenly Mrs Elise asked me if she could buy my sandwich from me. She explained that I could use the money to buy a hot hunch from the cafeteria (食堂).
I was excited. I never bought my lunch at the cafeteria. It was too expensive for my family, and I always carried my lunch and took the bag back home to use it again the next day. So you could understand my happiness when I had the chance to buy a hot lunch.
When we finished lunch that day, Mrs Elise took me aside and said she wanted to explain why she had bought my sandwich. I really didn’t care why, but it gave me a few minutes of her special attention, so I was quiet as she explained. She told me that she was a Catholic(天主教徒) and Catholics didn’t eat red meat on Fridays, they ate fish on Fridays.
Oh, I couldn’t wait to get home and tell my mother that from then on I wanted a tuna fish sandwich on Fridays. After my mother understood why, she gladly made tuna fish sandwiches for me on Fridays. She even made it with brown bread because she knew Mrs Elise liked brown bread. From then on, every Friday I could get in line with other kids for a hot lunch. I didn’t care how many of the kids complained about cafeteria food. It tasted divine to me!
I realize now that Mrs Elise could have made herself tuna fish sandwiches on Fridays. But she bought mine because she saw a little girl who was excited at the simple act of having a hot lunch.
I will never forget Mrs Elise for her pity for me and generosity (慷慨) and what I should do is to follow her example.
